Atheism versus Theism

Alright, I want a good, clean fight.  Simply state your side, your argument/counter-argument/comment and whatnot.  I'm not trying to troll this, just wanting a good debate, so let's have one. (Atheist by the way)

There is on difference between atheism and theism. The idea of God is not well-defined - it could have multiple definitions. However, the idea of God is to take on any idea, then it could be anything. Simply put, if God is to be omnipotent, or at least "almighty," then anything could be caused by God at all. Suppose a rock falls. It could have been caused by God. Or it may not have. There is no difference. Suppose some matter levitates or appears and assembles in a formation of a structure of an animal (which, of course, probably never happened). Perhaps God has done that. Or perhaps it naturally happened. There is no difference between the two.
